To all whom it may concern Be it known that 1, JOHN APPLETQN' Gone, acitizen of the United States, residing in New York, borough ofManhattan, and State of New York, have inventedcertam new and usefulImprovements n .W 1r1 n g Systems, of which the following 1s aspamfication.

This invention relates to wlrmg systems, and more particularly to acombination of parts which bring about a novel arrangement of the wiresand the mode of operation in connection with the same.

The object of the invention 1s to provide a wiring system by means ofwhich one or all lamps may be put into the electric circuit.

For this purpose my lnventlon cons sts of an improved wiring systemcomprlslng a conductor, a second conductor, lamps 1n circuit with saidconductors, an auxiliary conductor in circuit with one of sald lamps, aswitch in said auxiliary conductor, and a switch in one ofthefirst-named conductors and in the auxiliary conductor, said lastnamedswitch being capable of connectmg all the lamps in circuit with themalnconductors, and of connecting the single lamp in said auxiliaryconductor circult.

In the accompanying drawing, F1gure 1 shows a diagrammatic view of mylmproyed wiring system with the switch in posltion for lighting all thelamps, and F 1g. 2 1s a diagrammatic View of the swltch when in positionfor lighting only the single lamp through the auxiliary circuit.

Referring to the drawing, the conductors 70 and 73 are connected with asource of electric current, the conductors 70 being connected with onepole thereof and also with one pole of a lamp at 72, and Wlth the polesof a bank of lamps 51 at 71. The other conductor is capable ofconnectlon with the other pole of this single lamp 50 or bank of lamps51, depending upon the operation of switches inserted in the circuit.The other conductor 73 is also connected with an auxiliary conductor 75,which has a switch 76 arranged in the circuit thereof and the free endof which conductor 75 is connected with terminal 4 of a switch 15, whichis also in the circuit of conductor 74, said conductor 74 beingconnected with terminal 3 of said switch 15. Depending upon theoperation of the switch 15, either of the lamps oronlypne lamp, namely,lamp 50, maybe laced in the circuit of the conductor 70fand.

,The switch l5 of special construction, as,.for ;Xample,-shown inthepatent granted May 13 1913, to Joseph J. Wesley, No. 1,061,647, wherebwhen the switch is in one position, connection is vmade betweenterminals 1 and 3, and 2 and 3, while in another position the connectionbetween terminals 2 and 3 is broken and only a connection made betweenterminals 1 and 4.

When the switch 15 is thrown into one position, the pole 3 is connectedwith the pole 2 and 1, and thereby the current will flow through theconductor 70, poles 72 and 71, through the lamp 50 and the bank of lamps51, through the switch 15 conductor 74 and return through the conductor73, thereby lighting all the lamps. When, however, it is desired tolight only one lamp, namely, the single lamp 50, then the connections asshown in Fig. l are broken and the switch 76 is operated and by means ofthis the current flows through the conductor 70, pole 72, lamp 50,switch 15, conductor 75, switch 76 and returns through conductor 73, thebank of lamps 51 thereby being thrown out of circuit.

Fig. 1 shows an example of a practical use to which the switch may beapplied in a dwelling. The bank of lamps show three lamps of achandelier, and the 'lamp 50 shows a fourth lamp'of the same chandelier,placed preferably, for instance on the main floor of the house. Theswitch 15 is located in the same room with the lights 50 and 51 of thechandelier, as for instance in the dining-room on the main floor of thehouse, while the switch 76 may be located in a bed room upstairs. Bymeans of this arrangement a light may be turned on in the dining-roomdownstairs by an operator in the bedroom upstairs, and in the event thatan intruder in the dining-room should attempt to manipulate the switch15, he would instead of turning off the light 50, operate the switch insuch a manner as to turn on all the lights on the chandelier.

The improved wiring system provides thereby an approved means ofsupplying a longfelt Want and may be used not alone for the purpose suchas set forth, but also for any other and similar (purposes.

I have shown one embo iment of my inthrough the vention, but changes maybe made therein without departing from the spirit of the invention.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

A wiring system, comprising a main conductor, a second main conductor, aswitch between said conductors, a single lamp connected with the firstconductor and one terminal of said switch, a bank of lamps connectedwith said first conductor and another terminal of said switch, saidsecond main conductor being connected with a third terminal of saidswitch, an auxiliary conductor of the same polarity as the second maincon-
